AUGUST SOHNEELOOl-I, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO JOHN E. THOMAS, OF SAME PLACE.

TYPE-WRITING MAcHlNE.

SPECIFICATION forming part of Letters Patent N0. 647,035, dated April 10, 1,900.

Application led November 25, 1898. Serial No. 697,339. (No model.)

To all whom. t may concern:

Be it known that I, AUGUST SoHNEELooH, a subject of the Emperor of Germany, residing at the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Im provements in Type-Writing Machines, of which the following is a speciication, reference being had therein to the accompanying drawings.

My invention relates to type-writing machines; and its object is to provide a rapid and accurate key-action for such machines, the parts of which may be readily disconnected and put together again and which will admit of the independent adjustment both of the printing-point and of the bearing of each type-bar.

To these ends my invention consists of a device for actuating the type-bar from the movement of the keylever, comprising an auxiliarylever and connecting-link, of a new journal or bearing for the type-bar, of an adjustable hanger for such journal, andof certain details in construction.

I attain the objects by the mechanism illustrated in the accompanying drawings, in which similar letters indicate similar parts throughout the various views.

Figure 1 is a side view of my device applied to a visible-writing machine. Fig. 2 is a section on line-2,2 of Fig. l. Fig. 3 is a section on line 3 3 of Fig. l: Figs. 4. and 5 are detail views, respectively, of the hanger and heel of the type-bar, showing the bearing for such type-bar. Fig. 6 is a detail view of the auxiliary lever. Fig. 7 is a section on line 7 7 of Fig. 8, and Fig. 8 is a detail view of the connecting-link.

The mechanism is shown in the drawings adapted to that class of type-writing chines in which the writin g is visible to the operator.

A, J, and I indicate parts ofthe frame of` tively, to operate in the slotted bearing-openopening j, by means of which it is fulcrumed on at pin or bar j, supported in part J of the frame. The key-lever G is operatively connected with said auxiliary lever F by means of pin 7L and open slot f.

In providing means for operating the typebar from the movement of the key-lever it is-important that the connecting mechanism be quick-acting, so that there should be the least possible amount of 10st motion between the parts. I accomplish this in my device by making all the joints and bearings pivotal and not a combination of pivotal and sliding bearings. The key-lever G, Fig. l, is fulcrumed on rod t', supported by part I of the frame. O is a spring abutting against keylever G on knob 71. thereon and against screw P in frame I, whereby an adjustable spring tension of the key-lever is provided.. Said lever G is provided with pin h, operating in open slotf of lever F, so as to work said lever F upon its fulcrum j as said lever G is worked upon its fulcrum. Connecting-link E communicates motion from lever F to typebar D, being connected with them, respectively, by the pivotal bearings c fand e d. The dotted lines show'the position of the parts when the key II is depressed, the only sliding motion of the action being an inappreciable amount of pin h in slot f It is also important that the several parts of the key-action may be readily disconnected independently of the rest of the machine for Vpurposes of cleaning, repairing, and the like.

I therefore have provided a new system or combination of open joints or bearings and a new split bearing for the type-bar.

Great difliculty has been encountered in producing a typewriting machine in. which the alineinent of the writing produced thereby is and may be maintained accurate. A

Vcommon method of accomplishing this result is by changing the position of the type d on type-bar D. As the type is soldered to the bar, such a method of adjustment involves delay and. expense. By moving the journal IOO on the type-bar toward or away from the printing-point of the platen the desired result may be accomplished. I provide for such adjustment of said journal inthe following manner: Said journal is carried by the hanger comprising the parts K and L and means for uniting them. A slot is formed in said hanger by the cut-away portions 7a and Z, respectively, of the parts K and L. A setscrew Q-passes through this slot, screwing into segment C and holding the hanger in position. When the set-screw is loosened, the hanger may be raised or lowered, so as to bring type CZ into proper alinement. Grooves o in the hanger operating with slides or rails c on the segment may also be employed to give steadiness to the hanger and guide it as it is being adjusted. It is also important that the action of the type-bar be free from vibrationand accurate, and at the same time it should be allowed to operate with as little friction as possible. I have provided a new journal embodying these features and means of adjusting said journal, whereby the proper action of each type-bar may be easily maintained as the machine becomes worn by use. My new journal is also dust-pi'ooF,\\-'l1ich is one of the principal features of my invention, and I do not limit myself to the particular construction described-as, for instance, the grooves on the heel and the rings on the pieces K and L might be transposed without departing from my invention. I now proceed to describe said journal.

Referring to Figs. 2 to 5, inclusive, the heel D of the type-bar is extended so as to provide room on each side of said extension of the heel for similar circular grooves CZ", concentric with each other. Each of the parts K and L is cut away, so as to leave on each a circular rib or ring Zo and Z, respectively, said rings being adapted to operate or oscillate one in each of said grooves CZ, and so as to form the only points of contact between said extension ot' heel D and said parts K and L. Said parts K and L, I then place upon said extension of heel D, so that ring Zr; fits in one of the grooves CZ" and ring Z in the other of said grooves, and screw the parts together by screws n and n. The whole is then attached in any convenient manner in its proper position on segment C. Additional steadiness may be given this journal by providin g bearing-opening cZ" in heel D concentric with grooves d and similar bearing-openings in pieces K and L concentric, respectively, with rings Zc and Z and passing through the bearing-opening thus formed the typebar bearing-pin M, which is held in position by nut fm. It will readily be understood that a second leverage is thus obtained and that ,by the regulation of bolt-pin M the journal may be properly adjusted. From this split journal the type-bar D may also be readily removed.

The parts of the key-action may be assembled as follows: The type-bar having been adjusted, the Hat pin e of the connecting-link E is inserted in the bearing-opening CZ of the type-bar and the flat pin e of said connecting-link is inserted in the bearing-opening f of the lever F, and then the bearing-opening f ot said lever F is adjusted upon the iiat pin or bar j. The pin Zt ot the key-lever G is then placed in the open slot f ot' said lever F, and when the open bearing at the rear ot' said key-lever has been placed upon the rod t' the several parts will be held in proper position by adjusting-spring O.

What I claim, and desire to secure by Letters Patent, is

l. In a key-action for type-writing machines comprising a key-lever, an auxiliary lever, an oscillating type-bar, and a connectinglink, the means of rendering said parts readily separable frorn each other and the machine consisting of a split journal for the type-bar, slotted bearing-openings in said type-bar and said auxiliary lever cooperating with flat pins on said connecting-link, a second slotted bearing-opening in said auxiliary lever coperating with a at pin or bar on the frame of the machine, an open slot in said auxiliary lever cooperating with a pin on said key-lever and a half-open bearin g-openin g on said key-lever cooperating with a pin or rod on said frame.
